4.2.3 Discuss current estimates of numbers of species and past and present rates of species extinction
4.1.1 Define the terms biodiversity, genetic diversity, species diversity, and habitat diversity
2.3.4 Define the term diversity
4.1.4 Explain how plate activity has influences evolution and biodiversity
4.1.2 Outline the mechanism of natural selection as a possible driving force for speciation
4.1.3 State that isolation can lead to different species being produced that are unable to interbreed to yield fertile offspring
4.2.1 Identify factors that lead to loss of diversity
4.2.4 Describe and explain the factors that may make species more or less prone to extinction
4.2.6 Describe the case histories of three different species: one that has become extinct, another that is critically endangered, and a third species whose conservation status has been improved by intervention
